At the westernmost end of Hohhot, at the junction with Wuchuan County, Baotou City, the 100MW concentrating solar ground power station project of A-share listed company is under intense construction.
What is different from the past is that the power station not only adopts the light tracing system and the 7 times concentrating system, but also designs two step-up links (the first to 35 kV, the second to 220 kV). Among them, the purpose of chasing light and 7-fold focusing light is to maximize the reception of sunlight per unit area and minimize the use of photovoltaic cells. The purpose of boosting twice is to reduce power loss during long-distance transmission. In summary, this investment is focused on one goal: to increase the power generation of photovoltaic power plants, "the project manager told reporters.
Under the policy guidance of the National Energy Administration and other departments with the aim of "electricity subsidy", local governments and photovoltaic projects, especially concentrated ground power station projects, are increasingly fond of "power generation", which is undoubtedly a good phenomenon. Benefiting from this, on the one hand, the Chinese photovoltaic industry has launched a competition to seek higher power generation through technological innovation (on the basis of meeting certain economic standards); on the other hand, Financial institutions also have a parameter to follow, which enables them to better provide financial support for photovoltaic projects.
Compared to the booming centralized ground power plants, the other development path of photovoltaic is not so lucky, as the benefits of "surplus power grid" are far lower than the income of "self use". However, the "self use" part of power generation cannot be guaranteed (owners cannot use it), and seeking financial support has always been the most headache problem for distributed photovoltaic projects.
However, what has been circulating in the industry recently - the upcoming New Deal - may be able to change this situation.
The new policy plans to include "photovoltaic projects within 35 kV of grid connection, with power generation below 20000 kW, and effective use of mudflat, barren mountains and wastelands, agricultural greenhouses, and fish ponds" into the distributed category, and provide subsidies for local ground power stations.
On June 25th, the reporter learned from authoritative channels that the new policy has reached a consensus within the National Energy Administration and is being countersigned by the National Development and Reform Commission and the Ministry of Finance. It should be noted that unlike the previous version, the new policy will be included in the distributed category of "photovoltaic projects utilizing tidal flats and fish ponds", excluding barren mountains, wastelands, and agricultural greenhouses.
Moreover, in addition to the above-mentioned project categories, based on existing successful cases, rooftop distributed projects that meet certain requirements are also expected to enjoy the grid electricity price of centralized ground power plants. This will effectively clarify the benefits of distributed photovoltaics and enhance the attractiveness of remaining power online benefits to projects and financial institutions.
An official from the Ministry explained to reporters that, "In addition to the National Development and Reform Commission and its subsidiary body, the National Energy Commission, the implementation of this policy also involves the Ministry of Finance (the Renewable Energy Development Fund), so the two ministries will countersign. However, in the process of policy formulation, the opinions of the relevant parties will be fully solicited. Therefore, countersigning is only a necessary process for inter ministerial coordination, which also means that the release of the new policy is almost imperative.".
Ding Wenlei, the executive director of Aerospace Solar, who was also informed of this news, told reporters that the new policy will be implemented in Shandong, Jiangsu, Zhejiang, Guangdong, and industrial developed areas in the central and eastern regions (with high electricity consumption). In his view, the new policy has increased the income of distributed photovoltaic surplus power grid, and weakened the boundary between "spontaneous self use" and "surplus power grid".
According to the new photovoltaic installation plan formulated by the National Energy Administration last year, China plans to complete a photovoltaic installation capacity of 14GW this year, including 6GW for ground power stations and 8GW for distributed photovoltaics. However, it is widely believed in the industry that the installation task of 8GW distributed photovoltaic is difficult to complete.
The industry's reasons are simple. Taking the desulfurization price of 0.4469 yuan/kWh in Shandong region as an example, the current revenue from distributed photovoltaic power generation on the internet is about 0.8 yuan/kWh (0.4469 Yh plus subsidies issued in 0.42 years). The self use income can reach around 1.2 yuan/kWh (the general industrial electricity consumption is about 0.85 yuan/kWh, plus the national distribution subsidy of 0.42 yuan/kWh).
The income from self use is much higher than the income from grid connection of surplus electricity, which leads to the fact that almost all Almost all distributed photovoltaic systems strive to pursue the mode of full self use or off grid from the beginning of design. However, in this way, issues such as difficulty in settling self use electricity bills and uncertainty in project returns (changes in owners, fluctuations in electricity consumption) are highlighted, ultimately leading to financial institutions disdaining distributed loans.
However, the upcoming new policies have effectively addressed this issue. Ding Wenlei introduced to reporters that the income level of distributed surplus electricity internet may reach 1 yuan/kWh in the future (new policies will be implemented in the central and eastern regions, with most of the three types of solar resources enjoying 1 yuan/kWh grid electricity price), which is about 25%, higher than the current 0.8 yuan. "This will first improve the return on investment of distributed PV, but also make the benefits of distributed UV more clear, and promote Financial innovation in the photovoltaic field.".
